A Product Line Tailored for Underground Mining Excellence

SHOWCONN’s underground core drilling rig series (QZ-300, QZ-700, QZ-1000, QZ-1300) is meticulously crafted to address the unique challenges of underground exploration—from narrow tunnels to deep ore body sampling. Each model delivers targeted performance, covering a wide range of drilling depths and core sizes to suit diverse mining projects:

1. SHOWCONN QZ-300: Compact Power for Mid-Scale Exploration

Ideal for small to mid-sized underground mines, the QZ-300 balances agility and performance, making it perfect for preliminary geological surveys and shallow ore sampling.

· Key Specs: 45KW motor power, 660Nm spindle torque, and drilling depths up to 500m (for 46mm drill holes). Compatible with NQ/AQ drill rods, it yields core diameters of 27-48mm.

· Underground Advantage: Compact dimensions (3800×1500×1200mm main body) and 2100Kg total weight enable easy maneuvering in narrow tunnels, while ±90° vertical and 0°-360° horizontal drilling angles support multi-directional sampling.

2. SHOWCONN QZ-700: Reliable Performance for Medium-Depth Drilling

Engineered for medium-depth underground exploration, the QZ-700 excels in metal and coal mines, delivering consistent results for ore body delineation.

· Key Specs: 55KW motor power, 700Nm spindle torque, and maximum drilling depth of 700m (for 59mm drill holes). It supports HQ/NQ/BQ drill rods, producing core diameters of 36-63.5mm.

· Underground Advantage: 90KN axial tension enhances drill rod stability in deep holes, while the load-sensitive hydraulic system adapts to rock hardness, reducing energy waste and tool wear.

3. SHOWCONN QZ-1000: High-Power Solution for Deep Ore Exploration

The QZ-1000 is built for large-scale underground mines, tackling deep ore body exploration with unmatched torque and drilling efficiency.

· Key Specs: 75KW motor power, 1000Nm spindle torque, and drilling depths up to 900m (for 59mm drill holes). It accommodates HQ/NQ/BQ drill rods, with core diameters ranging from 37-63.5mm.

· Underground Advantage: 120KN axial tension ensures stability in ultra-deep holes, while the modular design simplifies maintenance in underground environments—critical for minimizing downtime.

4. SHOWCONN QZ-1300: Heavy-Duty Rig for Ultra-Deep Underground Projects

As the flagship model, the QZ-1300 is designed for ultra-deep underground exploration, meeting the demand for large-diameter, deep-length core drilling in high-yield mines.

· Key Specs: 90KW motor power, 1800Nm spindle torque, and maximum drilling depth of 1400m (for 59mm drill holes). It supports PQ/HQ/NQ/BQ drill rods, delivering core diameters of 37-85mm.

· Underground Advantage: 140KN axial thrust and tension handle the toughest rock formations (uniaxial compressive strength >80MPa), while the compact footprint (same main body dimensions as smaller models) ensures compatibility with existing underground infrastructure.

Core Technological Advantages for Underground Excellence

SHOWCONN’s underground core drilling rigs integrate industry-leading features to solve pain points in underground mining exploration:

· Load-Sensitive Hydraulic System: Adaptive drilling technology automatically adjusts power based on rock conditions, improving energy efficiency by 30% compared to conventional rigs and reducing operational costs.

· All-Angle Drilling Capability: Hydraulic-adjustable base enables ±90° vertical and 0°-360° horizontal drilling, eliminating the need for complex rig repositioning and supporting multi-directional ore sampling—critical for accurate geological mapping.

· Durable Clamping Mechanism: Spring-clamping + hydraulic-release design ensures reliable drill rod fixation, extending component life by 50% and reducing maintenance frequency—essential for 24/7 underground operations.

· Efficient Feeding System: Cylinder direct-drive feeding delivers 60-95KN axial thrust, ensuring stable penetration in hard rock while simplifying maintenance. The pilot-controlled operation panel reduces operator fatigue, with soft and minimal hydraulic impact for long shifts.

· Surface-to-Underground Versatility: Compact, modular design not only excels in underground tunnels but also adapts to complex surface environments, enabling mines to standardize equipment across exploration phases.
